Analysis and detection of fingerprint creases
Fingerprint is a biometric trait that is widely used for human identification and verification. Most fingerprint biometric systems make use of certain salient features on the fingerprint, including minutiae points, pores, and singular points, for comparing two fingerprint images. In this work, we …

An industrial revolution for fingerprint science? The impact of cognition and human factors on fingerprint examiners: implications for the use of fingerprint examiner expertise and administration within law enforcement.
Fingerprint analysis has been a cornerstone of law enforcement investigation for well over 100 years (Block 1970, Duncan 1942, Holt 1936, Beavan 2001, Sengoopta 2003, Cooke 1932 and Charlton et al 2007). Fingerprint evidence has rarely been challenged by either the public or the judicial system. …
